Title: Particle detector
Inventor: MORIYA SHUJI
IPC: H01L21/203
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To accurately detect particle generation states in a vacuum chamber on time by irradiating with a laser beam an exhaust auxiliary chamber attachedly provided to the vacuum chamber by a laser beam irradiation means and detecting a reflected light from the particles. SOLUTION: An exhaust auxiliary chamber 8 is attached in an exhaust port 6 formed in the bottom side wall of the vacuum chamber. In etching processing, the exhaust gas flows through an exhaust path provided around the outer circumference of a suspected into a ring state, flows from the exhaust port 6 to the auxiliary chamber 8, and exhausted to outside the device via an exhaust path 78. A laser beam (L) of a prescribed frequency is irradiated from a laser beam irradiation means 94 provided on the side wall 86A of the auxiliary chamber 8 toward a laser beam absorption means 110. If particles are present in the exhaust gas and when the particles pass through an optical path in transmitting this beam (L), the laser beam is reflected so that the reflected light is scattered.  This scattered light is detected by a light detection means 126 provided on a ceiling wall 120 so that the presence of the particles is recognized.

Title: Hydraulic control device for power transmission device for vehicle
Inventor: ITO HIROSHI
IPC: F16H61/14
Filed: 1989-02-13
Abstract: PURPOSE:To prevent the occurrence of an engine stop by a method wherein the pressure of working oil from a lockup control valve to a fluid joint is always regulated to a given value by means of a lockup clutch pressure regulating valve, and the pressure is increased by a given value in response to the working of a lockup rapid release valve. CONSTITUTION:A lockup clutch pressure regulating valve 310 always regulates the pressure of working oil fed to the lockup clutch of a fluid joint from a lockup control valve 320 to a given value. However, during disengagement of the lockup clutch, working oil flowing out from the oil chamber on the engagement side of the fluid joint is released by means of a lockup rapid release valve 400 from the middle of a discharge passage. The pressure of working oil fed to the fluid joint in response to the working thereof is varied to a value higher by a given pressure by means of the lockup clutch pressure regulating valve 310, and release response of the lockup clutch is improved. This constitution enables prevention of the occurrence of an engine stop during rapid brake even a case a relatively low value is used for the decision reference value of lockup clutch engagement control.

Title: Input signal interrupt detection circuit
Inventor: YAMADA YASUHIRO
IPC: H04B3/46
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To obtain a reply of an output denoting interruption of an input signal at a high speed independently of a set value of a reference voltage of a comparator. SOLUTION: A resistor R1 deciding a time constant of a clamp circuit is connected in parallel with a clamp capacitor C1 to set the time constant smaller than that of a peak value circuit. When an input signal is interrupted, since a discharge time of the clamp capacitor C1 is faster than a discharge time of a peak value capacitor C2, a peak value diode D2 is always nonconductive and the output voltage of a peak value detection circuit when the input signal is interrupted depends only on the time constant of the peak value circuit.
